Which of the substances A, B and C has the lowest heat capacity, if heat is supplied to all of them at equal rates? The temperature versus time graph is shown:
A
Substance having more heat capacity takes longer time to get heated to a higher temperature and longer time to get cooled. If we draw a line parallel to the time axis, then it cuts the given graphs at three different points corresponding points on the time axis show that tC>tB>tC or CC>CB>CA
